摘要
Abstract
To solve the fatigue damage problem of brake-disc splash shields of a particular SUV induced by random load excitation, their vibration-fatigue life is simulated based on Radioss modal frequency response results. According to the simulation results, a special structure called"round pit"is put forward for improving the local stiffness of mounting holes of the brake-disc splash shield for structure optimization. Comparison of the simulation results with fatigue testing results shows that the weak spots on the splash shield for fatigue life can be predicted accurately by using this method. Furthermore, the special structure"round pit"can be applied to increase the stiffness of components in order to optimize the structure design. Meanwhile, the project cost is efficiently reduced.关键词
